Topic: h.264 vs VP9 CPU utilization

For reference, all hardware acceleration is disabled and everything is being output to 1280x720 @ 90hz; I'm using the following as my test video (beware of on-screen f-bomb text at the end):https://www.youtube.com/watch?v=CEo1D2Y57_U

So I've run into an interesting issue with my new Pentium G3258...

For h.264 @ 1920x1080 30fps I can run perfectly with profile 4c.

But for VP9 @ 1920x1080 30fps, in order to run perfectly, I have to use profile 3c.

I mean, yes I could just stick with 3c and live with it, but it's kind of psychologically disappointing when it's only using like 45% of my CPU...I mean, I can run the same settings on 60fps 1920x1080 h.264!

Here's a screenshot I took showing the CPU utilization of h.264 @ 1080p 60fps vs VP9 @ 1080p 60fps without SVP and all hardware acceleration disabled:
